Description
Technical Field
The invention belongs to the technical field of design and preparation of nuclear material devices, and particularly relates to a nuclear ray protection glove and a preparation method thereof.
Background
With the continuous improvement of the modern scientific and technical level, various basic researches and technical developments developed around the application of atomic energy in the fields of nuclear power energy, medical detection, military wars, aerospace, civil security and the like are continuously increased. However, atomic energy is a double-edged sword, which greatly promotes the huge development of energy industry, modern medicine and military and promotes the progress of social history on one hand; on the other hand, the damage of harmful radiation to the natural environment and the injury of human body are attracting more and more attention.
In special fields such as nuclear industry, facility maintenance, equipment operation, radio isotope production, and the like in a radioactive environment require sufficient radiation protection for operators. Under special conditions, the hands of operators need to be contacted with radioactive substances, and the radiation protection gloves for the nuclear are particularly important. The traditional ray protection gloves made of lead rubber have the following weaknesses: on one hand, the traditional slurry dipping method manufacturing process cannot enable the lead rubber gloves to obtain high powder filling rate, and on the other hand, the extremely high density of the lead powder enables the lead powder gloves not to form a stable suspension state in rubber latex, so that the lead powder gloves cannot be uniformly dispersed in a rubber matrix, and the lead powder gloves and the rubber latex ultimately affect the protection efficiency of the gloves. Meanwhile, lead has many disadvantages as a radiation shielding material. On one hand, lead is active in property, easy to oxidize and biotoxic, and easily generates dust particles which are suspended in the air to cause harm in the processing and storage processes. According to the RoHS directive, WEEE directive and REACH regulation of the European Union, lead is listed as one of the hazardous substances that limit use and are of high concern. The higher grain size and surface state of the lead powder lead the interface bonding of the rubber/lead powder to be extremely poor, and further lead rubber gloves are easy to crack in the using process and lose the ray protection function. When the lead rubber gloves are used, the extremely fine lead particles exposed on the surfaces of the lead rubber gloves directly contact the skin of a human body, and health threats are extremely easy to generate. On the other hand, the lead rubber gloves produced by the slurry dipping method have low filling amount of lead particles, and the weak absorption region effect of lead makes the gloves have poor protection effect on X and gamma rays, so that the traditional lead rubber ray protection gloves are difficult to meet the actual use requirement, and particularly have poorer applicability under the environment of facing complex rays, such as the presence of neutrons.
When the glove is prepared by adopting the dipping method, tungsten powder, bismuth oxide powder and the like have high density, so the tungsten powder, the bismuth oxide powder and the like are easy to settle in the mucilage, and the dipping method cannot be used particularly when the filling amount is large. Therefore, the gloves prepared by the dipping method have lower powder filling amount, so that the protection efficiency is low, and the same lead equivalent requires larger thickness and weight. The gloves prepared by compression molding have high powder filling amount, high protection efficiency and smaller thickness and weight of the same lead equivalent, but have poor mechanical property and poor flexibility because of higher filling amount, and are easy to crack along a joint line when in use.
Therefore, it is very important to develop a nuclear radiation protection glove which can effectively avoid the pollution of lead element to the environment and the damage to the body of an operator in the processing and using processes, has good radiation protection performance, and is suitable for being used in a complex radiation environment.
